Corriere dello Sport says Eto'o's agent, Claudio Vigorelli, has been in contact with United this week about the Cameroon King's availability.

Eto'o is now in negotiations with Anzhi about a release from his contract and he has spoken this week about a return to Inter and also being reunited with former Nerazzurri coach Jose Mourinho at Chelsea.

The striker's wife Georgette and their four children are still living in the centre of Milan and a deal with Inter would be considered. But his personal terms will be difficult for Inter to match.

Chelsea have told Vigorelli they're keen, but must offload some players to make room for Eto'o.

Along with United asking to be kept up to speed on developments, AS Monaco and AS Roma have also been in contact with Vigorelli this week to register their interest.
